WINDMILI..V

SPECIFICATION forming part-of Letters Patent No. 432,146, dated July 15, 1890.

Application filed September 24, 1889. Serial No. 324,924. (No model.) l

To @ZZ whom, it may concern:

Be it known that I, OREIN W. PARKER, a citizen of the United States, residing at- Oakland, Alameda county, State of California, have invented an Improvement in Viudmills; and I hereby declare the following` to be a full, clear, and exact description of the same.

My invention relates to certain improvements in windmills; and it consists in certain details of construction which will be more fully explained by reference to the laccompanying drawings, in which- Figure l is a side elevation of a wheel, showing the vanes in position to stop the mill and the means whereby this result may be produced by the action of a float in the tank. Fig. 2, Sheet 2, is a side elevation showing the vanes in position to rotate the wheel. Fig. 3 is arcar view showing the vanes thrown out of the wind. Fig. fi is a horizontal section taken through the tubular support mand the segmental rods which connect the upper and lower portions through said tube.

A is the supporting-frame of the mill, having the tubular standard B fixed upon a top and suitably braced. C is the wheel-casting, having journal-boxes D upon it, in which the horizontal shaft E of the wheel turns. The. frame C is fitted to swivel or turn upon the upper part of the tube B, being supported upon a collar or fiange, as shown at F.

The shaft E hasacrank fixed upon the end just above the tube B, and a pitman G, connectingwi th said crank, extends down through the tube and connects with the pumping apparatus below. On the opposite end of the shaft E is fixed a hub or support II, having suitable radial boxes or supports, within which are fixed the radial arms or shafts I, corresponding in number with the number of vanes .I of which the wheel is to be composed, and these vanes are provided with lugs or boxes K, by which they are attached to the shafts L, so that they may turn around upon these shafts and either present their faces angularly to the wind, so as to be propelled by its action upon them, or they may present their edges to thewind, so that no rotary action will take place.

I prefer to make as few vanes as possible,

so as to present as great an area as possibleof each vane to the action of the wind, and also to reduce the mechanism necessary to operate the van es. The shaflsl are connected with the vanes at one side of the centralline, so that the tendency of the wind blowing upon the vanes will be to hold them at the proper angle to allow the wheel to be rotated.

pon the shaft E is a sliding hub or plate L, which isV connected by rods or links M with the inner corners or angles of the vanes J at points most distant from the shafts I, and when the sliding hub L is moved in one d1- rection it turns the vanes about their shafts I, so that they stand in planes parallel with the line of the shaft E, or with their edges toward the wind. XVh en moved in the opposite direction, the vanes are thrown into the angular position, which allows the wind to act upon them.

N is a cross or stop plate fixed upon the outer end of the shaft E, which acts to stop the vanes when they are turned into a position which throws the wheel out of the wind. The hub of the plate L has a groove or channel formed around it, into which the arms of the clutch-rod O fit, so that by the movement of this clutch-rod the plate L may be moved backward or forward upon the shaft E, as bcfore described. The rear end of this clutchrod O is connected with the end of a leverarm P, the opposite end being fulcrumed upon the wheel-casting O, as shown. A supplemental arm Q projects from the lever-arm P, forming an angular bend, sothat the outer end of the arm Q is connected with a rod R, which extends down inside of the tube B, and has a weight S attached to its lower end. This rod R is preferably made segmental in shape,having a considerable width and curved to the shape of the interior of the tube B.

y This form gives it considerable stiffness, which B. To the lower en d of thisarm T is fulcrumed a lever U, having a handle by which it may be moved, and the opposite end of the.

lever is connected with the arm R, so that when the lever is moved in one direction 1t IOO will act through the rod R, the arm Q, lever P, and clutch O to slide the plate or hub Lin either direction. Its object is to move this plat-e forward and thus turn the wheel-vanes parallel with the shaft and so that Jthe wind will not act upon them. Vhen this lever U is released, the weight S is sufficient to move the parts so as to again throw the vanes into the wind. If, however, the wind be very strong, it will be manifest that by reason of the vanes being journaled with the greater width upon one side of their supporti ng-shafts I than upon the other the action of the wind will be sufficient to overcome the weight S and to automatically turn the vanes more or less out ot' the wind, and thus relieve the wheel in case of too strong a wind.

In Fig. l I have shown a supplemental lever V, which is also connected at one end with the rod R, so as to act upon it in a similar manner with the lever U, and when its outer end is depressed the other end raises the rod Rand thus turns the wheel-Van es out of the wind. The opposite end ot' the leverV is ,connected by a cord NV, passing round suitable guidingpulleys X, with a :float Y within the tank Z, so that when the tank is full the rising of the float Y will allow the weight Ct to act through the cord WV upon the lever V, and through its connections to throw the wheelvanes out of the wind; but as the tank becomes emptied the ioat descending within it will raise the weight a, and thus allow the lever V to move, so that the vanes may be again turned into position to rotate the wheel.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

'lhe regulating apparatus consisting of the sliding collar connected to the vanes and its operating-rod and lever, a weighted regulating-rod R, depending from said lever, a similar rod T, hun gfrom the wheel-casting, a handlever pivoted to the lower part of the rods T and R, anda lever V, pivoted to the lower part of the frame ot' the mill and engaging under a pin on the rod R, and the tank and its float connected, as described, to the lever V, substantially as described.

In witness whereot` I have hereunto set my hand.
